Features and Scope: 9Cr18Mo 9Cr18Mo is to produce stainless steel bearing rings and rolling with a high carbon chromium stainless steel. Stainless steel cutting tools used for slicing and cutting machinery tools, surgical blades, high wear equipment parts. 9Cr18 high carbon martensitic stainless chromium bearing steel. After quenching with high hardness and wear resistance, high temperature, low temperature dimensional stability. 9Cr18Mo characteristics and uses essentially the same 9Cr18 steel, but with a higher hardness after quenching and temper resistance, molybdenum increase the passivation of stainless steel. 9Cr18,9Cr18Mo carbon chromium stainless steel ball Uses: Suitable for the manufacture of bearings in the bearing sea water, river water, nitric acid, steam, and marine and other corrosive media, such as ships, submersible pump parts of the bearing, the oil and chemical machinery, marine instrument bearings. Chemical composition: Si Si: ≤0.80 sulfur S: ≤0.030 phosphorus P: ≤0.035 Ni: to allow contains ≤0.60 Mo Mo: can join ≤0.75 Mechanical Properties: Hardness: annealing, ≤255HB; quenching and tempering, ≥55HRC treatment specifications and microstructure: heat treatment specifications: 1) annealing, 800 ~ 920 ℃ slow cooling; 2) quenching, 1000 ~ 1050 ℃ oil cooling; 3) tempered, 200 ~ 300 ℃ oil, air cooling. Microstructure: Organizing for the martensitic. Delivery status: generally heat treatment delivery, the treatment types specified in the contract; not indicated, by not heat treatment delivery. Characteristics: high hardness and wear resistance of medium, when polished, its drawback is relatively large viscosity, and temperature quickly. Uses: Suitable for corrosion resistance (magnetic) cutlery (knife), after the turbine blades hardened steel hardness ratio increased 440A (magnetic), blades, nozzles, valves, board feet, cutlery (scissors).
